Turbidity Sensor

In accordance with USEPA Method 180.1 for turbidity measurement, the Turbidity Sensors are a 90 degree scatter nephelometer. The turbidity sensor directs a focused beam into the monitored water. The light beam reflects off particles in the water, and the resultant light intensity is measured by the turbidity sensor's photodetector positioned at 90 degrees to the light beam. The light intensity detected by the turbidity sensor is directly proportional to the turbidity of the water. The turbidity sensors utilize a second light detector to correct for light intensity variations, color changes, and minor lens fouling.

For environmental or process monitoring, simply place the turbidity sensor directly in the water and position it where the turbidity is to be monitored. Since the turbidity sensor uses light to detect the water's turbidity ensure that the minimum amount of external light possible is exposed to the monitoring site.

Turbidity Meter

The Global Water Turbidity Meter combines the turbidity sensor (described above) with a handheld meter that has a six digit LED screen, 4-button control panel, and an internal 9V battery. The handheld portable turbidity meter can be used for environmental or process sites that do not require permanent monitoring. The turbidity meter will display readings directly in either nephelometric turbidity units (NTU) or parts per million (PPM). The turbidity meter also includes an automatic shutoff feature to conserve battery power.

Turbidity Sensor Cleaning and Use

To maintain accurate readings with your turbidity sensors the lenses should be cleaned a minimum of once per week. Depending on the monitoring site, the turbidity sensor's lenses may need to be cleaned as much as once per day. The turbidity sensor has been designed for harsh field conditions and uses the latest manufacturing design technology.
